Nanopositioning Actuators suit limited-space applications.
Press Release Summary:
Featuring non-rotating tip, M-2x series motorized linear actuators are self-contained packages consisting of dc or stepping motor connected to ball screw or lead screw. They integrate non-contacting limit switches, homing sensors, and piezo-tip with 1 nm min incremental motion is optional. Suited for OEM and research applications, products provide design resolutions to 4 nm, pushing forces to 26 lb, and speeds to 2 ips. Maximum travel is 2 in.
Original Press Release:
Nanopositioning Actuators Combine High Speed, Resolution & Force
Auburn, MA. Nanopositioning Specialist PI, provides the M-2x series of high-precision motorized linear actuators for applications requiring very high resolution, high force and high speed.
Unique Combination of Speed, Resolution and Force
The units provide design resolutions to 4 nanometers, pushing forces to 120 N (26 lbs) and speeds to 50 mm (2 inches) per second. A piezo-tip featuring 1 nm minimum incremental motion is available as an option.
Designed for OEM and Research Applications
The M-2x series actuators are self-contained packages consisting of a DC or stepping motor connected to a ball screw or lead screw. Unlike many other motorized actuators, the M-23x series features a non-rotating tip which ensures maximum stability and motion linearity.
Integrated non-contacting limit switches and homing sensors increase the versatility and help to protect sensitive equipment in applications where extended motion could cause damage.
Versatility: DC and Stepper Motors, Folded Drive-Train
Both stepper and closed-loop DC servo motors are offered. The DC motor versions come with a closed-loop high-resolution encoder, which allows minimum incremental motion of 50 nm.
For applications where space is at a minimum, an ultra-compact version featuring a folded drive-train (parallel drive shaft / motor configuration) is available.
Typical Applications: Instrumentation Small Machinery, Micro-Machining, Semiconductor Test Equipment, Biotechnology, High-Precision Micropositioning and Nanopositioning,
